ATTORNEYS sents the casing of a gate valve forming a part of the pipe or line 1, and including the gate ,5 valve seat 6, gate 7 and stem 8 for operating the gate. The stem passes through asuitable j stulfing' bOXQ. Anysuitable type of valve may be used, but a gate valve has thus far been found to give the best results. The connection.

of the operating element 8 canbemadein any preferred manner but is here shownasmade by means or" a pin 10; the end of the element 8 being in threaded engagement withthe gate 7. I

.Means isprovided and rconnected to op erate-the valve to open and' close it, thus controlling'fiow through the sewer dram pipe to prevent overflow at the receiving end -2 of the pipe 1. Inthis instance, the means inst mentioned include, pressure operable devices; a float arranged at alevel below the open end 2 of the pipe '1, and a connection establishing communication between pipe and the float, so that saidfloat is operated as the result of sewer back-hp and therefore by means of liquid or even gas pressure set up in, the sewer drain pipe as thelresult' In other words, this lnterflood conditions. communicating connect on provides means by whlch the back-up effects are available to float or equivalent element being connected with. the sewer pipe valve operating means so that whenever back-up pressure; or liquid p level, has reached a predeterminedfigure th drain'pipe control valve" is closed. I uAlthoughevery detailof construction of 7 every part of the: now-to-be-described mechanism is claimed, there is no intention to be entirely limited to suchdetail inasmuch as i it is conceivable that other equivalent means and close it, includes a pressureroperable' device having a cylinder 15 suitably supmaybe employed for obtaining automatic closing of the flood-preventing valve as the resultofpressures or equivalent effects crej ated by the flow of liquid, or of gas, in a di rection'toward the opening 2;

Themeans to operate the valve 7 to open ported and having a piston 16 to one side of which the connector 8 is secured by threading as at 17. The connector 8 passes" through. a suitablestufling box 18. "A guideirod 26 is connected as a 19 to the oppositeside of the -piston and extends upwardly througha' suit able stufiing box 20. This rod also functions as means for operating a valve-which controls the city water supply to a toilet flush valve (not shown) so that when the valve 7 is clos ed,, no great additional; quantity of sewage can be introduced through the toilet waste pipe during a floodperiod and when the gate {valve is closed, It iis assumedfthat.

the sewer pipe 25 leading from a toilet or toilets enters the pipe 1 at a point between the gate valve7'and the openend 2 of the pipe -1. "It .is obvious that while the gate 7 is close d, anoverflow at 2 would occur if any great quantity of sewage were emptied into the pipe25,- from any source. It will be understood that the valve 27 which is operatedtby the guide rod26-is located in the flush 'water line sothat its closing does not affect the fiow t-hrough the water lines and gate controlvalves dater'to bedescribed. Any suit' k" able connection be made": between the guide rod 26 and the valve 27 for-example a connectionisuch' a's shown in Figures 2and 7,- comprising' a valve stem 21, a lever 22 for operatingthe -stem, said lever having a slot 23 through which a pi n 24. loosely passes,

which pin is suitably threaded. int'othe' guide rod 26." The valve is of the type which opens or closes when its stem is rotated through sition The sewer pipe 25 is supposed to vbe connected with a toilet-(or other device to be" flushed) although no such device has been 7 shown; Furthermore, the hush valve which would ordinarilyzbe'in the flush pipe line28,

V N p p v V v H and which would-deliver, byway ofthe toilet, operate the float or equivalentvde'vice, SLlCl into the pipe 25 hasnot'been shown. Figure 2 is therefore "in this respect diagrammatic, the idea being to provide means so thati no appreciable amount of waste or flush site sides of the piston 16, and the directions fioo of fluid flow are; best shown in Figure 7. 7

The house water supply pipe or other pressure pipeline is shown at-30, and this pipe has branches respectivelyindicated at 31-32 which deliver into opposite ends of the'cylinder15. Bra n'ch' pipes respectivelyindicated 3834 lead fronirespective pipes 5132, and

Interposed in branches 31 'l 2'-3334 a are valves {respectively designated 4041- 42-43. Referrin'gto'Figure 3, it will'be.

notedfthatthe valves 4041 have their stems 46 47 {adjustably connectedto a" common operatingelement: 45, alsosee Figure 4.

Thevalves 4Q.. 43-When open permit drain flow of Water respectivelyfrom the top and bottom or". thecylinder. The valves are so arranged that when valve 40 18 open water under'pressurels delivered to the top o f the cylinder-for closing the valve,

A feature of theinvention alsoincludesthe arrangement of each valve, seeFigu're .3,

whereby the fluidpressure is'applied in a manner to assist inholding the valves'closed,v

and in a manner to assist in shiftingthe valves either to open" or closed position, For this purpose, the pressure deliveryis at thepoint indicatedand in direction of arrow 51 With thedelivery at the point 51 as: shown, and r to the application of pressure to torce'the -piston16idownwardly1to close the-valve 7,

Means is also provided to operate the-valves just described in a manner to obtain proper movements of the-piston respectively to open and close the valve 7 andto maintain it in each limit position.

It will again be noted that the elements 4647 areadjustably connected with the'connector 45, see Figure 3.:

For this purpose the ends of element 46 are threaded as at 36,,and nuts 37- 37 provide means'for securing theelements 7 in adjustedposition which adjustment is merelymade by rotating the elements so that the threads feed inwardly or outwardly as desired; The samebadjustment is provided between the connector 50, and the valve stems 48'49.- It

is also possible that the'tension on the stems may be'varied, by thepacking boxnuts, to varythe sequence or" opening respect vely of 15 the waste and pressure control valves."

' Another feature of the invention includes :means whereby-the drain line 35,whi'ch is also a pressure line acts to. flush the connec L tion generally designated 66, and to thus prewhich permits access'to, a strainer element.

97 disposed to prevent the entry of sediment into the nipple 93 or into thefioat-operating or pressure connection. The drain pipe 35 leads into. the four-i'vay as at 36 in adirection to flushthe pipe 95; Thus. whenever I drainage is taking place through the pipe 35, the four-way? and the element 95 will be flushed, and a kind of injectoraction will .talre place during recession period of the back-up sewer pipe contents to assist in emptyingthe connection 66. Moreover, during the back-up period discharge through the waste 35 may LSS1SJD1I1 raising the float notwithstanding the fact that-the flowthrough the waste pipe is counter to thefiow from the v pipell through the connection 66.

Referring to Figure 1, it is to be again noted that the valves 40, 41, 42 and 43 have the intakes arranged so that water enters 'towardsthe face of the seat, as distinguished from an entry from the opposite direction,

so that intake pressure to the cylinder and outlet pressure from the cylinder assists in bringing the valves'to and holding them in their final positions. In other words, in the present invention, the pressure is first applied in the chamber which contains the head of the movable valve element;
